St-Laurent Caulking
St-Laurent Caulking is a high-performance, color-matched sealant designed to complement St-Laurent’s factory-finished James Hardie fiber cement products.
Ideal for sealing joints, corners, trim edges, and other transition points, this caulking ensures a clean, professional finish while protecting your exterior from moisture and weather damage. It offers excellent adhesion, flexibility, and durability, making it suitable for both new installations and repairs. Color-matched to St-Laurent siding and trim finishes, it helps maintain a seamless, uniform appearance across your entire project.
